A new mobile phone prototype emerges – and it doesn’t need any batteries!

No more charging!

For smartphone users, battery seems to be the most important thing they’re looking for in terms of features and with each new smartphone model that’s being released, one can only hope that the battery life can be better.

But researchers at the University of Washington have managed to create a prototype smartphone that can operate without the use of a battery.

But how will it work without a battery? Turns out, the device uses a tiny circuit board with a solar cell to draw power from outside light and even radio signals. It then uses the device’s microphone and speaker to simulate vibrations to encode incoming and outgoing signals from the device. They do this to conserve the battery, since the normal way of converting analog audio to digital data are the main reasons of battery drain.

At the moment, the device isn’t capable of receiving and sending audio at the same time, so it will not work like a normal smartphone but more like a walkie-talkie where you need to hold a button to say something.

Still, the researchers have committed on improving this prototype with the hopes of it evolving into a full pledged power source that does not need to be charged. This could possibly mean that future smartphone devices will no longer need to be charged – that’s one feature I can’t wait to have.
